Can not access customized WinRT component from different threads in Metro Style C# application

Question

Hi All:

  I meet a problem when we try to wrap our old library to WinRT Component. Here is the simplified situation:

  1, we create a simply WinRT Component use the standard WinRT Component DLL template.

  2, in our Metro Style C# Application, We create that WinRT Component object in one thread.

  3, Then when we try access that object in another thread, We got InvalidCastException.

Anyone have any clue about this issue?

BTW:

   Seems there is no problem If we use that WinRT Component in  Metro Style C++ Application in same method.
